WebMetamorphism ends when the rock begins to melt. True or False e What is the most efficient agent of metamorphism? A. cementation B. weathering C. chemically active … WebThis new information has required a reinterpretation of metamorphic facies in many cases. Field studies support the laboratory data. Experimental studies of rock melting have shown that water pressure drastically reduces the melting temperatures of sediments and igneous rocks. Similar studies with other volatiles show additional strong effects.

WebThis can happen when rocks are buried deep underground and are exposed to high temperatures and pressures. This process, known as metamorphism, can turn sedimentary rocks into metamorphic rocks. 5. Melting: When rocks are exposed to extremely high temperatures, they can melt and become magma. This magma can then cool and … WebRocks exposed to high temperatures and pressures can be changed physically or chemically to form a different rock, called metamorphic.
